| Abstract: | Optimization of bio-oxidation-CIL after cyanidation process gold leaching process was carried out in Sanhe gold mining company.The processing capability was increased by 42.49 t/d with the optimization of bio-oxidation operation parameters.Through adding a two-staged process for precipitating oxidation elution solution to recover high grade gold-containing micro fine oxidation residues,applying two-staged precipitation-filter pressing process to recover carbon power and supplementing with a gravity separation process using tables to recover gold from cyanidation slags.Thanks to these measures,total recovery of gold was increased by 0.46 % and annual gold production by 884.4 kg,achieving notable economic benefits. |
